c. In one-on-one interviews which are the most common type you will sit down with a company representative to discuss the position and your qualifications.

Answer 1

Answer: option A is the correctly punctuated sentence.

Explanation: “which are the most common type” is a non-restrictive modifying clause. A nonrestrictive modifying clause is a phrase that adds nonessential information to the sentence without altering its meaning, and, therefore, should be in a set of commas.
